Precipitrons

The first electrostatic cleaner, invented by Westinghouse in 1935, was transferred to Sturtevant after the takeover and was produced till the mid-70s when commercial products were de-emphasized.

The Precipitron was a highly efficient device for removing dust, dirt, smoke, soot and other solids from normal ventilating air. Its operation was based upon the fundamental concept of electric charge - bodies of like charge repel and those of unlike charge attract. Dirt particles in the airstream were given electrical charges as they passed through an ionizer and were trapped in dust collector cells by attraction of these charged particles to plate surfaces of opposite polarity.
